and since bubba is 5 lbs - I would ask your vet and get some protection like Frontline Plue or Advantix right away - you don't need a prescription for it but you DO need to treat him - and the DAWN Dish soap really works but is only a TEMPORARY FIX and don't get it near his face or eyes - it would sting
